Luckily, Williams hasn't let the commentary about her physique slow her down. Three days after securing her second "Serena Slam," the tennis pro took to Instagram today to show off her fit body in a striped and polka-dotted navy bikini top from a beach in Sweden (above).

From the looks of things, she hasn't let critics get to her—and even addressed them in an earlier post while getting her eyebrows done. "Lol finally getting them shaped! Hahahha #haters I love you!!! Hahah but I still like them all natural! But for now you win lol" she wrote in the video's caption:

One of Williams's fangirls Harry Potter author J.K. Rowling also had some words for a detractor, who heckled Williams's figure on Twitter. Rowling jumped in and replied with picture of champion and captioned it, "Yeah, my husband looks just like this in a dress. You're an idiot."
